Organizes a word list by the length of the words.

For a source word list, see @neopass/wordlist

import { WordsByLengthView } from '@neopass/words-by-length-view'

// Use a set to avoid duplicate words.
let words = new Set([
  'some', 'words', 'in', 'a', 'list',
  'to', 'be', 'organized', 'by', 'length', 'by', 'the', 'view',
  'this', 'can', 'also', 'be', 'a', 'promise', 'that', 'returns', 'a', 'list',
  'or', 'a', 'wordlist', 'list', 'builder', 'function',
])

// Create the view, converting the set to an array.
const view = new WordsByLengthView([...words])

// Allow the set to be garbage collected.
words = null

// Get all words by length.
const allWords = view.get()
console.log(allWords)

// Get words of length from 3 to 6, inclusive.
const someWords = view.get(3, 6)
console.log(someWords)
